Losing display output after 5 minutes
-
I’m have been running into a issue over that past week, were the HDMI connection will drop and the TV will stop displaying. I have check TV setting for a sleep mode, changed out Raspberry Pi’s, updates, and replaced the micro card. I do have the background changing ever 60 sec and still the TV will lose the HDMI signal. Looking for other troubleshooting steps.
-
@danjvd are you sure it’s the display turning off ?
if you do alt-spacebar does the appenubcome down?
if so, this means the app has crashed, leaving a black screen
-
@sdetweil I’m able to VNC to the pi, and when I move the mouse the TV will turn back on. It will then stay on for 5 minutes before TV lose HDMI connection. I have also keep the VNC connection open and watch the TV lose signal and the app continue to work.
I have missed with the PI config file to increase the HDMI signal but same outcome.
Also, I did setup CEC, 6 months ago, to control when the TV turns on and off. I was thinking there was an issues with the pi, so I created a con job to turn the TV, then restart the PI. This setting worked for about a week. Now if I do not restart the PI it comes up with no HDMI signal.
I wondering if its an issues with the TV itself?
-
@danjvd if you stop MagicMirror, does the screen turn off?
-
@sdetweil I have not tried that. I will let you know later today of the outcome.
Thanks Sam!

@danjvd It sounds as if your screen saver wasn’t disabled correctly?

@zoltan if u run my install script it will turn off screensavers if u say yes.
also a separate script if u change your mind
we are still waiting to see if it’s mm related or not

@danjvd ok so this means one of the modules you are using is turning off the display
can you do
grep module: ~/MagicMirror/config/config.jsto show us a list of the modules used
-
@sdetweil said in Losing display output after 5 minutes:
grep module: ~/MagicMirror/config/config.js
Here are the modules that I have been using for the past 6 months before the issues started. I have not added/removed any modules after this setup, only updates.
module: "alert", module: 'MMM-BackgroundSlideshow', module: "updatenotification", module: "clock", module: 'MMM-CalendarExt2', module: "MMM-OpenWeatherMapForecast", -
@danjvd weird.
so next I would disable one module at a time.
(not the defaults)add
disabled:true,after the module: line

Before I was able to start disabling modules, MM would not start this morning. There are the logs that I got from pm2:

Give you a little update after finding the error above. I have reinstalled dependency and built electron.
cd ~/MagicMirror npm install cd ~/MagicMirror/node_modules/electron/ node install.jsThe reinstall came with the following warnings
npm WARN tsutils@3.21.0 requires a peer of typescript@>=2.8.0 || >= 3.2.0-dev || >= 3.3.0-dev || >= 3.4.0-dev || >= 3.5.0-dev || >= 3.6.0-dev || >= 3.6.0-beta || >= 3.7.0-dev || >= 3.7.0-beta but none is installed.

Error found: Error: Cannot find module 'valid-url' Require stack: - /home/pi/MagicMirror/modules/MMM-CalendarExt2/node_helper.js - /home/pi/MagicMirror/js/app.js - /home/pi/MagicMirror/js/electron.js - /home/pi/MagicMirror/node_modules/electron/dist/resources/default_app.asar/main.jsI disable that mode and was able to get MM restarted. I’m guessing there is an issue with MMM-CalendarExt2.
